The DS-20 is a compact and capable monohull sailboat, designed as an accessible cruiser with a focus on maximizing interior space for its size. Crafted by the collaboration of Diller & Schwill, and built by DS Yachts (also known as Schwill Yachts) in Odessa, Ontario, the DS-20 was in production from 1972 to 1983. It gained a reputation as a practical and well-designed small sailboat, particularly suited for recreational sailing.

The DS-20 emerged from the Canadian boat-building efforts of DS Yachts, a company founded by Herman Schwill in 1971. The builder's philosophy revolved around creating accessible, well-designed small sailboats, known for their durable fiberglass construction. The DS-20, like its popular sibling the DS-16, was a product of the design partnership between Herman Schwill and naval architect G. Diller.

Production of the DS-20 commenced in 1972 and continued through 1983. During its production run, a Mark II version was introduced, offering more interior amenities. While most DS-20s were equipped with a wing keel, some variations featured a shallow draft fixed keel, providing options for different sailing preferences and shallow water access. The company primarily focused on fiberglass construction, a material that revolutionized boat building by offering durability, lower maintenance, and more efficient production compared to traditional wood.

Sailing Performance and Handling

Though a smaller vessel at just over 20 feet in length, the DS-20 is characterized as a light sailboat with good performance capabilities. It boasts a theoretical maximum hull speed of approximately 5.7 knots. Designed with a fractional rig, the DS-20 features smaller headsails, which can contribute to ease of handling. While some owners have described it as a "slow" boat, it is generally considered a good, well-built vessel for its size. The DS-20 is often best suited as a day-boat, offering a stable and stiff platform for its class, though its righting capability if capsized is considered low.

Accommodations and Layout

Despite its modest length, the DS-20 was designed to provide surprisingly generous interior space, aiming for maximum volume within its cruising design. The cabin offers an impressive 4 feet 10 inches (1.47 meters) of headroom, a notable feature for a boat of this size, and provides a good amount of storage. While specific interior layouts can vary, particularly between the original and Mark II versions which offered more amenities, the design generally focuses on practicality and utility for recreational cruising. The use of fiberglass for the hull and deck suggests a relatively low-maintenance finish, common for boats of its era and class.

Owner's Perspectives

Owners of the DS-20 frequently commend its solid construction, noting that there is "enough glass" in the hull, indicating durable fiberglass build. Its well-built nature is a consistent point of praise. Some owners have noted that the boat is easy to maintain, requiring minimal effort for bottom cleaning and anti-fouling painting annually. Recurring issues mentioned by some owners relate to potential fuel starvation problems with outboard motors, suggesting that attention to fuel systems is advisable. The existence of active owner communities and forums speaks to the enduring appeal and functionality of the DS-20, with boats from the early 1980s still actively sailed today.
